Suspicious fire?

Fire at UW Lab

So, last night there was a fire at the UW Molecular Biology Lab . .. that's scary on a lot of levels, the news reported radioactive materials, but some of the chemicals in Molecular Biology Lab are FAR scarier than radioactives.

In any case, this struck me as another example of PC action aftermath.
The Mad Scientist has created his creature in the Molecular Biology Lab. It's up to the PCs to destroy the creature before it can escape and start converting new victims into part of its mass.

Of course the players have to burn the creature and the doctor's twisted notes. The remains leak toxic chemicals and radioactive materials.
